Typedef Documentation

typedef uint16 ipv6port

IPv6 port number.

Function Documentation

unsigned fmt_ipv6addr	(	char *	buffer,
		const ipv6addr *	addr
	)

Produce a formatted string from an IPv6 address.

The given buffer must be at least 39 bytes long, or 40 bytes if it needs to contain the standard trailing NUL byte.

Returns:

The number of bytes written to the buffer.

Note:

This routine is thread and recursion safe.

const char* ipv6_format

(

const ipv6addr *

addr

)

Produce a formatted C string from an IPv6 address.

Note:

The return value is statically allocated. Multiple calls to this function will return pointers to the same string.

const char* ipv6_scan	(	const char *	s,
		ipv6addr *	addr
	)

Scan a C string for an IPv6 address.

Returns:

NULL if parsing failed, otherwise a pointer to the first character after the end of the address.

Variable Documentation

const ipv6addr IPV6ADDR_ANY

IPv6 "any" address constant.

const ipv6addr IPV6ADDR_LOOPBACK

IPv6 loopback address constant.
